Answer:
An association between two organisms in which one benefits and the other derives neither benefit nor harm.
Explanation:
Answer:
Answer is B. It did not reflect the actual evolutionary relationships among organisms very well.
Explanation:
The five-kingdom system of classification was initiated or formed by Robert H. Whittaker in 1969. And it involved the Kingdoms monera, fungi, protista, animalia and plantae.
This classification system was regarded as not so good because of placement of some certain organisms. For example, in the classification system, unicellular algae were put under the kingdom protista, when other multicellular organisms like algae were being classified under the kingdom Plantae.
Cell plants contain chloroplasts which have the pigment chlorophyll which absorbs deep-blue and red light, so that the rest of the sunlight spectrum is being reflected, and cause the plant to look green.
Answer;
Light microscope
Explanation;
-A light microscope is an instrument that uses visible light and magnifying lenses to examine small objects not visible to the naked eye, or in finer detail than the naked eye allows.
-Light microscopes use a single lens to magnify an object and cannot reach high magnification. Illuminator is the light source for a microscope, typically located in the base of the microscope.
Answer:
1- substitution.
2- neutral.
Explanation:
The change in the genetic sequence of the organisms known as mutation. Mutations might be sudden and heritable in nature. spontaneous mutation and induced mutation are types of mutation.
A change that causes a change in single base pair of a gene sequence is called substitution mutation. The original leucine sequence is GTT and the mutated sequence is GTG. Thus T has been substituted by G.
Mutation can be beneficial, detrimental or neutral. The neutral mutation is that does not affect the physical change. Both GTT and GTG code for the same amino acid so it would be neutral.
